I live in an apartment building that includes wireless internet with our rent, the problem is my apartment only picks up the signal in a certain place by the window and not in the bedroom. I have a Time Capsule laying around. My question is, can I run a ~50ft ethernet cable from the router next door (my landlord and neighbor are okay with this) into my Time Capsule and 'extend' the network so my apt has good coverage? The wireless router currently in use is a 5Ghz dlink router (I'm guessing it is the 5Ghz that is killing the short distance and inability to go through walls). Would I set the network up to create a new one or extend an existing one? Security: Can I keep other people on the network from accessing my time capsule HD in this setup? Would it be possible to password protect the time capsule HD with one password and share a disk connected to it via USB with another password to serve as a shared disk on the network? Thanks!
